To el?, who-m it mcy concern:

Be it known that l, PERLEY R. GLASS, a

citizen of the United States, residing in Beston, county ol" Siillolk, and State of Massa-,

ehusetts, have inveritci'l an lmprove'n'ient in (lement-Apgdying Mechanism, of whichthe following L .n.-riptiom in connection with the acconiliiinj'ing drawing, is a specification, lilac letten; on the drawing representing like parts.

' Prior to my invention, a nozzle adapted'to be supplied with cement has been provided with a valve, the nose ofwhieh normally projects therefrom and prevents the delivery more cen'ient when the stock increases inthirkness.

l iind in practice that diiferent kinds of stock' require more or less ceInent,-and this Whether the stock is thick or thin, and consequently .l have combined with the valve. referred to as coacting with said nozzle means whereby' 1 may set the valve so that it may be opened by contact with the stock fur enough to ierm'it only a defi nite quantity of cement to ow onto the stock, any increase in thickness of stock not increasing the iiow of cement, or in other words I have combined with 4the valve referred to means whereby the valve inay be opened for 'any desired -extent by contact with the stock, and any increase of' thicknessin the stock will raise both the nozzle and the valve without fu'r* ther' openin the valve.

'Figure 1-1 ri side elevation shows part ol" a shine' with which l have enibodied my invention in one of the best forms-now known lo nie., Fig. 2 is mi, enlarged longitudinal section broken .through the nozzle showin -the val-ve in elevation; Fig. 3 is a view looking,r atthe nozzle and its connected valve adjusting devices Fig. 4 is a top end View ofthe parts shown in Fig. 3, and 1`ig. 5 is a modification 'sln'iwil'ig my improvement applied to a hand` operated i-.einenting device.

` Referring to the drawings, A represents the base, A. an overlianging arm,4 Al a shaft provided at one end with a driving ulley A and at it I -Cm resiiu tliat it may e moved toward the stock sup'- oppoeixe wid with a stoe h1-ding feeding disk for actinfy on the 'up er side of the stock resting on vtile feeding wlieel, B its carrying shaft, B"l a pulley on said shaft driven from a'belt B"l from the wheel A?! The parts so far described are and may be es in common use. The overhanging arnis'us tains a een'ient receptacle C having aplunger on the cement therein, the lower part of said receptacle having a co'elc C that when turned into'its opent-position admits cement into a nozzle D having a valve D2 that is normallyclosed by a spring e when` the toe of the valve'is not in contact with the stock to which cement is to be applied. This' receptacle, nozzle and valve, and closing spring with the nozzle however maintained stationary on the framework, is not he'reiii claimed broadl but I am, as l. believe, the first to move the nozzle" vertically after the valve has been opened to any predetei'mined I defree by means to behereinefter described.

have shown in Figs. 1 to 4 my novel ce-` i'n-i-.nt applying mechanism as applied to a machine of usual construction, but it will be understood that my improved mechanism may he used to apply cement to leather or to 4other substances sustained in anyusual mam nel' and. in any niachin commonly used to feed leatheroi' other material. When they stock, Sustained by a feedingrwheehis fed regularl under theV nozzle, and the stock uniformly on the stock. l y

In my invention I haveproyidd means to sustain the nozzle andlsto'c support -i'n yielding relation so that in ease ,the Stock-,varies in thickness one or 'the other yield, but' without opening the valv .eyondtlie pointv predetermined by the amount of c'ement to 4 e delivered, and in illustratii'ig ni'y invention, I have ,herein chosenv ososupport the nozzle that it may yield w'V h relation to the stock support, but a converse relation weuld come within the broad .scope ofmy invention.l Consequentl l. have shown the nozzle so port, the nozzle being represented as emiraced Vloosely b a f ixed partei the head of tlie machine. 'lhis nozzle'4 may therefore rise and fall under the influence of a spi-ing .the upper end of which is attached to 'a' opens t e valve, cement -Will be delivered.

stud y/ extended from the upper end of the uozzo, the lower end of'saidfspi'ing being runner-ted with :i stationary stud g' extended foon n psrti'if the frame. The stud a eonnected with the valve D and extended out- Wardly through the slot a in said nozzle has fitted toit a striker a?, that is moved 1n unl son with said valve, said striker when the valve moved in the direction of the arrow thereon by contact with the stock to thus open a space f or the exit of cement, contacting with. a regulating device b, shown .as

slotted to receive a set screw b', the outer end of said device being acted upon by an adjusting device b2, the movement of which may slide the regulating device so that the space left between the tapered upper end oi said striker en d the tapered under side of said regulating device may be made more or Iless to thereby predetermine in advance just "fthe space it is desired to leave between the 'upper side of the Work on the beveled edge 10 of the valve sind theeat 14 of the nozzle. The nozzle also supports at its lovverend a Work gage 4ltshtnvn as extended below the right'hand side. thereof against 'which may bear the edge of a piece of stock :With-the toe l2 oi the valve 'and raises 'the same against the spring `-e until the upper end of the striker meets the regulating device. Now ifthe stock should increase in thickness, the nozzle and. valvelrise together out kfurther opening-the valve.

I have provided the extension D3 from the nozzle with en adjustable stop screw m that contacts with a roection fm2 risinf` from the framework, the stop 1nl eing so'adjllls'ted asy to'{,irevent the toe ofthe valvcvcontacting Wit i the feeding device; j

y As so `far desea-Hoed,-theinaehine in use will lay aline-0l` 'cement on the stock.

I'believ'e that I nm the first 'to provide a nozzle with' avulve ,provided with. n. projection With an-.adjustal'vlc regulator,change of position of which provides [or varying the opening,oljspanze-le'ft by the movement of the valve: to" thereby l`deliver -a `redeterillined cpantity `of eelnent.- Accor( ingly I have s own in Fig. 5 a nozzlefl) to begra'sped by hand,\the valve Dhaving its connected stud a extended outwardlytlirough a slot d". This stud in Fig. '5 isacted upon by a spring ex that serves normally to-seat the stud .inthe lower .end of said slot and kee the valve so seated to prevent the escape o cement. 'lo the outeil side'of the nozzle, I have attached by a set vscrew n, a regulator shown as a slotted plate, the shank of 'the screw being extended through said slot to maintain the same ina position in which it may be ad-A justed accrding'to the' Width of the space it 1s desired to leave when the toe of the valve acting against the stock causes said valveto be moved and enter said nozzle. t
